ACETYLEN E-GAS LAM P.

SPECIFICATION forming part of Letters Patent No. 655,261, dated August 7, 1900.

Application filedNovember 7,1899. Serial No- 786,133. (No model.)

To all whom it may concern:

Be it known that I, GEORGE ARBUTHNOT MOORE, a subject of the Queen of England, and a resident of Bromborough, county of Chester, England, have invented certain new and useful Improvements in Acetylene-Gas Lamps, of which the following is a specification.

This invention has reference to acetylenegas lamps such as are used for vehicles, for domestic purposes, and the like; and it has more particularly for its object, amongothers, to provide improvements in such lamps by which the carbid stored in a lamp and not being for the moment used for the making of the gas shall be capable of being stored or held Within the lamp or in a part connected with it in such a manner that it will be wholly unaffected by the moisture of or about the lamp and the container or from any source, and consequently will remain absolutelyinert and undeteriorated as long as it is not in actual use.

The invention is illustrated in the an nezied drawings, in which Figure 1 is a sectional elevation showing a lamp provided with the improvements hereunder; and Fig. 2 is a plan in section taken at the line A A, Fig. 1, while Fig. 3 illustrates in section a number of charges of carbid of calcium piled one upon the other and made up according to this invention.

According to this invention the carbid is made up in comparatively-small quantities or charges in suitable proportions to the size of the gas container or vessel, and these charges are so inclosed or wrapped up that while they are within the chamber or reservoir where they are stored no vapor or moisture within the lamp or, in fact, no dampness can reach the carbid; but when they are fed from the container or reservoir (which is effected seriatt'm by suitable mechanical means) and delivered to the place where they are converted to gas by water they cease to be water and damp proof, and access of water to the carbid is provided.

Referring now to the drawings, a represents the gas-making chamber of the lamp,

comprising an outer cylinder at, a bottom plate I), and a cover or top plate 0.

d is a tube extending between the cover 0 r and the bottom plate b, constituting the carloid reservoir or container, this tube being made gas-tight with c and b where it enters them, and d is a cap on the lower end of the tube d, through which the carbid charges are introduced. 6 represents a spring in this tube, which normally is under the carbid charges and forces them upward.

f is a carbid-feeding device, it being in the form of a disk disposed in a chamber 9 on the top of the cover 0 and adapted to move charges of carbid from the tube cl to the chamber ct. This disk has a chamber'g within it, While at an equal distance from the centerviz., from the axle h'-an aperture 0' is provided in the cover 0, with which the chamber g will coincide when the disk is rotated half a revolution. Over the disk f there is a cover or cap 2', which screwsonto the chamber g and incloses the whole device, the actuatingspindle it alone projecting through this cover.

The lower part of the body a. is provided with a tube j, having a screw-cap j, by means of which the body a may be charged with water, and the bottom 19 is provided with a screw-cap b, by taking ofi which the lime deposit left in the chamber a may be removed.

In action assuming the reservoir (1 to have been charged with carbid in the form of a plu rality of separate charges and these charges to be pressed upward by the spring 9, by moving the feeder-disk f, so that its chamber 9 is coincident with the upper end of the reservoir d, it enables the spring e to press the upper end of the pile of charges in (1 up into the chamber 9, and then by turning the disk around by its operating-handle it half a revolution this charge, filling more or less the chamber g, will be carried from the reservoir to a point over the opening 0', when it will fall from 9 through the opening into the water in a, and acetylene gas will be generated. This gas may be burned at the burner. is, to which it flows from the chamber a past regulating or stop valve Z and a pipe m.

With regard to the charges of carbid, they top and at the sides, but not at the bottom;

but they are rendered proof against the en:

try of moisture evenat this part also by the envelop p. In use a pocket of capsuled charges thus made is placed within the .res-

ervoir-tube d, and when the feeder-disk -f,--

with the chamber 9 standing over the mouth of d and the upper capsuled charge within it, is turned by the handle h thisuppermost charge will be removed, the impervious envelopp, of waterproofed paper or other suitable material, bein gin this action shorn across at the division-line between the two upper capsules,.and when this separate capsule falls into the water in the chamber a the water has access to the carbid through the open or p'ervious end of the capsule. The remaining capsuled charges, however, in the reservoir will be impervious to the entrance of moisture, and soon as each charge is removed and fed from the reservoir to the gas j makingchamber those remaining are unaffected and'proof against the access of moisture to them internally. Hence even if moisture or moist gas does reach the reservoir 11 more or less, this moisture cannot affectthe carbid in the capsules, and it remains unacted upon and un deteriorated;

According to a modification, in lieu of the capsules being constructed as just described they may consist of waxedpaper or equivalent waterproof. material and be practically hermetically closed. In such a case when they are being .fed to the lamp gas-making chamber each capsule as it is fed is perforated, so that when they enter the water it can have access to the carbid within. In

the lamp shown in-Figs. 1 and2' this P'llllO', turing is provided by a pointed punch 1' working .in a bearing in the cover z', the said punch being disposed over the tube (1. In action when the upper capsule enters the chamber g the punch 1' is pressed down-and method of'packing them, the mechanical With regard to this feature of the retention of the carbid charges in the reservoir in a condition in which moisture cannot get at them anddeteriorate them at all, besides the special characteristics of the lamp shownthemselves are such that the access of moisture to the The reservoir is extremely small, as the feedingdisk f itself forms a valve on the plate or cover 'zl,making a gas-tight joint between the gas-making chamber a and the reservoir 01. Hence the escape of gas or moisture from a to d cannot take place, and the only moisture which has access to it is through the cham ber g, which will be filled with gas after the feeding actionand will carry it from the chamber to the upper end of the reservoir tube 61. v I, The reservoir (1 beingfilled from the lower end, by removing the cap d it is totally out of communication and connection with any portion of the lamp containing moisture.

The amount of carbidconta'ined in each of, the capsules 0-that is, thecharg'es-should be of such size as will fill thechambers'a/with the required volume of gas at a suitablepressure, so that the lamp canbe worked for any elected period of time, and the continuous supply of gas is obtained by feeding the charges from the reservoir in which they'are I stored at intervals, as may be required, to the gas-making chamber. 7

It is to be stated that the invention is not restricted to the "form r of lamp andoperating mechanism shown in the-drawings, as these may be modifiedor-equivalents used without departing from its essential characteristics.
